"Someone has already set up Teams for your organization" error in Microsoft Teams

Symptoms

When you try to set up a Microsoft Teams account, you receive the following error message:

Someone has already set up Teams for your organization

Resolution

This issue may have several causes.

Cause 1: Someone has already set up Teams for you

Resolution:

• Look for a recent invitation in your email Inbox.
• Alternatively, open https://teams.microsoft.com from a private or incognito browser window. Then, enter your domain credentials to sign in.

Cause 2: Your email address is tied to both a work and a personal account

For example, you're using the contoso.com domain for both your Microsoft Service Account (Live ID) and your work account (Active Directory).

Resolution:

1. Open https://teams.microsoft.com from a private or incognito browser window.
2. Create a Teams account, and then sign in by using the credentials for your work or school account.
3. If it doesn't work, you must unlink the two accounts to create a free Teams account. For more information, see Change the email address or phone number for your Microsoft account.

Cause 3: You're trying to sign up for your work account by using a free tenant

For more information about tenant, see Tenants.

Resolution:

Use your organization's tenant for this account. For personal use, create a free Teams account by using a personal email address.
